Page 102Besides the features described above, in several ^-conjugated polymers one
observes a high-energy peak in photo-induced absorption, which is not
accompanied by additional IR modes and therefore corresponds to a neutral
defect.

Page 144In the case of trans-(CH)„ the energy of the two structures is the same, whereas
for e.g. poly(p-phenylene), it is not. In the latter material the quinoid state has a
higher energy than the ground state with the more benzenoid (aromatic) bond ...

Page 150The latter is in general a measure for the activation energy £C-£F. If the observed
conductivity has the same activation energy, conduction in extended states can
be assumed. 3.2.2 Conduction in Localized States Carriers in localized states ...
